Data Sources and Citation Metrics
The 5th edition of the Research.com Best Immunology Scientists in Greece Ranking is primarily based on comprehensive bibliometric data obtained from OpenAlex and CrossRef, along with multiple other reputable sources. These platforms represent some of the most prominent and well-established bibliometric databases available to the research community, ensuring a robust foundation for the ranking. The citation-based metrics used to determine each scientist's position were collected on January 12, 2026.
A researcher’s position in the ranking is determined by their D-index (Discipline H-index), an adapted metric that focuses exclusively on papers and citations within the specific discipline under examination—in this case, Immunology. This approach allows a more precise evaluation of scientific impact within the relevant field, rather than relying on general metrics.
Scope of Research and Qualification Criteria
The ranking process analyzed 187,135 scientist profiles drawn from a wide range of bibliometric databases encompassing all scientific disciplines. From this pool, 10 scientists specializing in Immunology in Greece were carefully examined. To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 40. Furthermore, a majority of their tier publications needed to be in Immunology. Awards and notable achievements in the field of Immunology were also considered as additional qualitative factors.
The D-index threshold is dynamically set in increments of 10 based on the estimated total number of scholars in each discipline, ensuring the inclusion of the top 1% of leading researchers. Another vital criterion for consideration is that the proximity between a scientist’s general H-index and their D-index does not exceed 30%, which guarantees appropriate alignment between their overall and discipline-specific research impact.
Verification and Secondary Assessment Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute evaluation tool, the ranking process involved meticulous manual verification of all scientist profiles. Researchers were cross-correlated against publications in a wide variety of trustworthy sources to affirm authenticity and relevance. While the number of publications in prominent journals and conference proceedings does not directly influence ranking position, it provides a valuable secondary signal of a scientist’s contributions to their specific area.
The ranking position is firmly based on each researcher’s D-index according to data extracted from OpenAlex, CrossRef, and other authoritative databases. These additional verification practices underline the careful and comprehensive work that went into creating a credible and reliable ranking framework.
